5 Claims. (o1. 155+1s4 The invention relates to cushioned seats and. a method of making the same.

Thegeneral object of the invention is to pro 7 the seat covering is firmly bound to the seat body 1 by a metal binding formed as a part of the metal seat body itself or a metal bindingring secured to said seat body, thus doing away with theriveting and subsequentstitching operations of the prior application and the leather binding thereof without, however, incurring danger of the binding cutting or otherwise injuring the covering, and so that the covering is firmly, yet yieldingly, held-at its outer edge portion.

A further object of the invention is to provide an upholstered metal seat in which all stitching, tacks, rivets, nails, and the like have been eliminated. v

,The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof. Inthe drawings: a j Fig. 1 is a plan View of a seat embodying the invention, parts: being broken away;

Fig. 2 is aside elevation view of the seat shown 1% in Fig. 1; V

Fig. 3 isa detailed sectional view taken on the line 3-3 of Fig. 1; r Fig. 4 is a detailed sectional view taken von the line 4-4 of Fig. 1; V

Fig. 5 vis a view similar to Fig. 3 showing certain modifications.

Referring to the drawings, the numeral 6 designates a seat body .of stamped sheet metal whichis deeply dished and curved for comfort and is provided with a flanged edge portion 1 which has an annular curved groove 8. formed therein on its upper side which forms a bead-9 on its lower side, the outer edge ofthis part 1 due to stamping being relatively sharp. Over the top surface of :the flanged edge 1 I secure a wear and anchor strip 10 which is cemented to said body by a coating of. naphtha-rubber cement or other suitable adhesive not specially shown in the drawings but disposed between said strip and body. The anchor stripflli is of heavy canvas, cut on the bias and placed on said top surface-so as to form allinirig therefor including the groove 8, the strip. l0 thus forming a band substantially coextensive with said edge 1 with its ends forming ,eitherva, butt or lapped joint. After cementing this strip to the body, these parts are'allowed to stand for a considerable time until the. cement has set, for example a period of twelve hours.

The cushioning material Il may be of any suitable kind, such as any suitable animal or vegetable fiber or rubber suchas sponge rubber. Where animal or vegetable fibers are used, they are preferably felted together in any suitable manner. The cushioning material herein shown is hair feltand'iifs secured by a coating of naphtha cement (not specifically indicated) to the metal seat body and ei llcnds over the entire seat cavity and terminates on about a level with the flanged edge portion 1. This cushioning material may be secured to the seat body by cementing it thereto at the same time that the anchor strip I0 is securedto the body, that is, the whole top surface of the body is given a coating of naphtha cement by respective portions of which the strip and cushion are secured to the body.

After the anchor strip, I0 is secured to the body, a cord I2 of yieldable material, such as rubber, hemp, cotton, or other suitable fibrous material, is either first coated with naphtha cement and then laid in and along the groove with its'ends fo ming a butt joint or the groove portion or said stripis coated with naphtha cement and thecord then laid in the groove.

Thereafter, a c'overing"l3 of'heavy duck canvas has'one side coated with a latex rubber cement, which coated side is laid over the top of the cushioning material, the cord l2, and the anchor strip IE3, and then directly after stripped therefrom leaving'a coating of'latex on the burlap covered side of the cushioning material as well as on theanchor strip and cord. Then these cement coated parts are allowed to stand until they become tacky, and then in this condition the cover applied to cement the coated side of the cushion, first at its center, and then outwardly along the sides, and then pressed against said material bya heavyweight. While thus weighted, the covering is stretched and drawn out over the edge portion of the seat and brought down into adhesive engagement with the anchor strip and cord while drawing it over the top edge of the cushioning material.

Thereafter, the covering [3 is given a heavy binding means comprises a band M of soft steel,v

brass, or other suitable metal which before its application to the seat is bent into'aform generally U-shaped in cross sectionwith its lower.

side I 5 of greater width than itstopandprovided with a lengthwise extending groove l6 which fits over and against the bead 9 and forms an interlocking connection therewith. The top side I! of the band initially formed so, as to slip over the top portion of the seat isgso positioned, and ,thenwhile holding the lowerjsidefllj" against the edge. portion], the top side I! is'bent'down into the clampedfposition shown in the drawings with its front. edge. l8, which may be jinitially slightly bent downwardly, engaging the top covering above the cord I2, and injthefinished assembly putting this. cord under compression by bendingjthe frontjedge18 of the band down wardly over said cord, thus firml'yjint'erlocking the covering andcord betweenjthe seat body and the band. The -end of the band may hav'ea butt joint or lap joint,flbutja butt, joint with a clip l9 overthe jo'intand spotjweided .or tightly crimped thereto as preferred.

Instead of the separate band .I1-.=I may form a seat body 6', as shown in Fig. 5, with an extended edge'zdwhich is'bent down over the covering l3 and cord I Zafter these parts have been position'ed on the seat bodyin the same manner as the firstldescribed construction, the edge portion I of .the :body having the groove 8" formed therein" similar to the groove 8 of the first construction. Theextended edge 20 when bent down has its front edge 2| bent'downwardly in'the same way the front edge 18 is formed on the ring I1 and acts in the same way to tightly clamp the covering and cord betweenit and the opposite edge'portion of the body. 1 e

From the-foregoing it will befnotedthat I have provided a cushionseat structure in which the binding for the top coveringis of metal and will last practioallyaslong asthe metal seat body.

It is further to be noted that the metal'binding means when brought into clamping engagement with the covering acts to force it into the groove 8 and in dOing s acts to draw the covering out smooth around the upper edge of the seat. It is also to be noted that the groove 8 or 8 forms a head in the outer edge portion of the seat body, and this has the very important advantage of acting to greatly reinforce the seat body, so that it will not become bent out of shape while in service and so that it may be made out of light enough gauge as to permit ready stamping. It is further to be noted that this beaded or corrugated edge is still further reinforced in the modified form shown in Fig. by the bent over extension 20.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

shown in Figs. 2, and 4; is

What I claim as my invention is:

2. In a seat, the combination of a dished metal seat body having a flanged edge portion provided with a groove coextensive therewith, a fabric anchor strip cemented to the top surface of said flanged portion over an area, including said groove, cushioning materialsecuredto said body, a compressible member mounted in said-groove, a covering of flexible material adhesively secured to said cushioning material and to=said anchor strip, and a metallic binding member having an interlocking connection withthe reverse side of said groove and a clamping engagement with said covering including an edge portion compressing said compressible member and forcing said covering downwardly into the groove. 7

3.
